I have added an optional product (lets call "X") to an product "Y". When i add the product Y to my cart and than i add the optional product X the quantity of product X its dependent on the quantity the product Y.

Is it possible to change that i can chose the quantity the product X independently? Example product Y x1, product X x3??

I had a look at product_bundle app; question: from a tax perspective, does this app allow to account for different tax rates according to the components of the bundle itself? use case is -inFrance - for music sheets taxed at 5.5% bundled with a cd which is taxed at 20%; The customer taxes must be the total of the two taxes.
